CALL: BARYCENTRE


histogram

  The histogram of which the barycentre is to be computed.

  Histograms are normally linked to global variables, they
  can be created via BOOK_HISTOGRAM, by operations between
  other existing histograms, or obtained from some commands
  with a KEEP-HISTOGRAM option.

  [No default]

barycentre

  On successful completion of the procedure, this variable
  is set to the barycentre of the histogram.

  This argument must be a modifiable global variable, not
  an expression, a constant etc. If the variable exists
  prior to the procedure call, then the associated value
  will be lost.

nbin

  An optional argument that specifies the window width
  used both for searching the peak and for computing the
  barycentre.
